• Eclipse Helios on OS X Snow Leopard crashes frequently when editing certain PHP files

  - by William

  I use Eclipse Helios (Eclipse Platform: 3.6.0.I20100608-0911, Eclipse IDE for PHP Developers: 1.3.0.20100617-0520) all the time on OS X (Snow Leopard), and it seems I only run into trouble whenever I'm editing a PHP file that's part of the WordPress blogging framework. When I move my cursor to a variable or function name, that often triggers the beach ball of death. I suspect Eclipse is trying to look up that variable/function and for some reason that causes an endless loop. Sometimes it's not just variables or functions. Just today I was trying to replace all occurrences of a quoted string. Every time I clicked "Replace All", the program would freeze immediately after the string was replaced and the text cursor was moved to the replaced position. I think the moving of the text cursor is important, because I got the same result when I searched for the string (thus moving the cursor), but NOT when I searched for a nonexistent string. I tried disabling everything in my preferences related to marked occurrences, hovering, code assistance, etc. Nothing helps. I use Eclipse for all my projects, and I find that it's only WordPress projects where this happens. Here's my eclipse.ini file: -startup ../../../plugins/org.eclipse.equinox.launcher_1.1.0.v20100507.jar --launcher.library ../../../plugins/org.eclipse.equinox.launcher.cocoa.macosx_1.1.0.v20100503 -product org.eclipse.epp.package.php.product --launcher.defaultAction openFile -showsplash org.eclipse.platform --launcher.XXMaxPermSize 512m --launcher.defaultAction openFile -vmargs -Dosgi.requiredJavaVersion=1.5 -XstartOnFirstThread -Dorg.eclipse.swt.internal.carbon.smallFonts -XX:PermSize=128m -XX:MaxPermSize=128m -XX:MaxGCPauseMillis=10 -XX:MaxHeapFreeRatio=70 -XX:+UseConcMarkSweepGC -XX:+CMSIncrementalMode -XX:+CMSIncrementalPacing -XX:CompileThreshold=5 -Xms128m -Xmx512m -Xss2m -Xdock:icon=../Resources/Eclipse.icns -XstartOnFirstThread -Dorg.eclipse.swt.internal.carbon.smallFonts -framework ../../../plugins/org.eclipse.osgi.services_3.2.100.v20100503.jar I have 4GB of RAM, so I don't know if the problem is I'm underutilizing my resources.

This value will be overwritten using the values from the preferences I did some experimenting with the particular script that's giving me trouble. It's a hybrid of HTML and PHP, so Eclipse has to do both HTML and PHP validation. I wondered if the HTML validation had something to do with it, so I created a new file, copied the contents over, and messed with the doctype element. I found that if I replaced the well-formed XHTML 1.0 Strict doctype element with a generic doctype (as such: <!DOCTYPE html>), then I did not crash the program just by moving the cursor around. I set all HTML validation rules to "Ignore", but it still didn't solve my problems. For now, I'm just going to echo the doctype using PHP instead of entering it literally. That seems to prevent crashes. I notice that when I move the cursor around the document, Eclipse displays the "xpath" to my current location at the bottom of the screen. Sometimes there's a delay while it figures out my current path. Perhaps when it's validating against the Strict doctype, it has problems quickly calculating the xpath as I move the cursor around? Maybe it has a stack overflow that causes it to crash.

• how can load images from plist in to UITableView ?

  - by srikanth rongali

  I have stored the videos and the thumbnail images of the videos in Documents folder. And I have given the path in plist. In plist I took an array and I added directories to the array. And in the dictionary I stored the image path /Users/srikanth/Library/Application Support/iPhone Simulator/User/Applications/9E6E8B22-C946-4442-9209-75BB0E924434/Documents/image1 for key imagePath. for video /Users/srikanth/Library/Application Support/iPhone Simulator/User/Applications/9E6E8B22-C946-4442-9209-75BB0E924434/Documents/video1.mp4 for key filePath. I used following code but it is not working. I am trying only for images. I need the images to be loaded in the table in each cell. - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease]; [cell setAccessoryType:UITableViewCellAccessoryDetailDisclosureButton]; UIImageView *image2 = [[UIImageView alloc]init]; image2.frame = CGRectMake(0.0f, 0.0f, 80.0f, 80.0f); image2.backgroundColor = [UIColor clearColor]; //image2.image = [UIImage imageNamed:@"snook.png"]; image2.tag = tag7; } NSDictionary *dictOfplist = [cells objectAtIndex:indexPath.row]; [(UIImageView *)[cell viewWithTag:tag7] setImage:[dictOfplist objectForKey:@"imagePath"]]; return cell; } - (void)viewDidLoad { [super viewDidLoad]; self.title = @"Library"; self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"Close" style:UIBarButtonItemStyleBordered target:self action:@selector(close:)]; NSString* plistPath = [[NSBundle mainBundle] pathForResource:@"details" ofType:@"plist"]; contentArray = [NSArray arrayWithContentsOfFile:plistPath]; cells = [[NSMutableArray alloc]initWithCapacity:[contentArray count]]; for(dCount = 0; dCount < [contentArray count]; dCount++) [cells addObject:[contentArray objectAtIndex:dCount]]; } How can I make this work.

• New Perl user: using a hash of arrays

  - by Zach H

  I'm doing a little datamining project where a perl script grabs info from a SQL database and parses it. The data consists of several timestamps. I want to find how many of a particular type of timestamp exist on any particular day. Unfortunately, this is my first perl script, and the nature of perl when it comes to hashes and arrays is confusing me quite a bit. Code segment: my %values=();#A hash of the total values of each type of data of each day. #The key is the day, and each key stores an array of each of the values I need. my @proposal; #[drafted timestamp(0), submitted timestamp(1), attny approved timestamp(2),Organiziation approved timestamp(3), Other approval timestamp(4), Approved Timestamp(5)] while(@proposal=$sqlresults->fetchrow_array()){ #TODO: check to make sure proposal is valid #Increment the number of timestamps of each type on each particular date my $i; for($i=0;$i<=5;$i++) $values{$proposal[$i]}[$i]++; #Update rolling average of daily #TODO: To check total load, increment total load on all dates between attourney approve date and accepted date for($i=$proposal[1];$i<=$proposal[2];$i++) $values{$i}[6]++; } I keep getting syntax errors inside the for loops incrementing values. Also, considering that I'm using strict and warnings, will Perl auto-create arrays of the right values when I'm accessing them inside the hash, or will I get out-of bounds errors everywhere? Thanks for any help, Zach

• Using the groupby method in Python, example included

  - by randombits

  Trying to work with groupby so that I can group together files that were created on the same day. When I say same day in this case, I mean the dd part in mm/dd/yyyy. So if a file was created on March 1 and April 1, they should be grouped together because the "1" matches. Here's the code I have so far: #!/usr/bin/python import os import datetime from itertools import groupby def created_ymd(fn): ts = os.stat(fn).st_ctime dt = datetime.date.fromtimestamp(ts) return dt.year, dt.month, dt.day def get_files(): files = [] for f in os.listdir(os.getcwd()): if not os.path.isfile(f): continue y,m,d = created_ymd(f) files.append((f, d)) return files files = get_files() for key, group in groupby(files, lambda x: x[1]): for file in group: print "file: %s, date: %s" % (file[0], key) print " " The problem is, I get lots of files that get grouped together based on the day. But then I'll see multiple groups with the same day. Meaning I might have 4 files grouped that were created on the 17th. Later on I'll see another unique set of 2 files that are also created on the 17th. Where am I going wrong?

• python: how to design a container with elements that must reference their container

  - by Luke404

  (the title is admittedly not that great. Please forgive my English, this is the best I could think of) I'm writing a python script that will manage email domains and their accounts, and I'm also a newby at OOP design. My two (related?) issues are: the Domain class must do special work to add and remove accounts, like adding/removing them to the underlying implementation how to manage operations on accounts that must go through their container To solve the former issue I'd add a factory method to the Domain class that'll build an Account instance in that domain, and a 'remove' (anti-factory?) method to handle deletions. For the latter this seems to me "anti-oop" since what would logically be an operation on an Account (eg, change password) must always reference the containing Domain. Seems to me that I must add to the Account a reference back to the Domain and use that to get data (like the domain name) or call methods on the Domain class. Code example (element uses data from the container) that manages an underlying Vpopmail system: class Account: def __init__(self, name, password, domain): self.name = name self.password = password self.domain = domain def set_password(self, password): os.system('vpasswd %s@%s %s' % (self.name, self.domain.name, password) self.password = password class Domain: def __init__(self, domain_name): self.name = domain_name self.accounts = {} def create_account(self, name, password): os.system('vadduser %s@%s %s' % (name, self.name, password)) account = Account(name, password, self) self.accounts[name] = account def delete_account(self, name): os.system('vdeluser %s@%s' % (name, self.name)) del self.accounts[name] another option would be for Account.set_password to call a Domain method that would do the actual work - sounds equally ugly to me. Also note the duplication of data (account name also as dict key), it sounds logical (account names are "primary key" inside a domain) but accounts need to know their own name.

• text-area-text-to-be-split-with-conditions repeated

  - by desmiserables

  I have a text area wherein i have limited the user from entering more that 15 characters in one line as I want to get the free flow text separated into substrings of max limit 15 characters and assign each line an order number. This is what I was doing in my java class: int interval = 15; items = new ArrayList(); TextItem item = null; for (int i = 0; i < text.length(); i = i + interval) { item = new TextItem (); item.setOrder(i); if (i + interval < text.length()) { item.setSubText(text.substring(i, i + interval)); items.add(item); } else { item.setSubText(text.substring(i)); items.add(item); } } Now it works properly unless the user presses the enter key. Whenever the user presses the enter key I want to make that line as a new item having only that part as the subText. I can check whether my text.substring(i, i + interval) contains any "\n" and split till there but the problem is to get the remaining characters after "\n" till next 15 or till next "\n" and set proper order and subText.

• SQL Query - group by more than one column, but distinct

  - by Ranhiru

  I have a bidding table, as follows: SellID INT FOREIGN KEY REFERENCES SellItem(SellID), CusID INT FOREIGN KEY REFERENCES Customer(CusID), Amount FLOAT NOT NULL, BidTime DATETIME DEFAULT getdate() Now in my website I need to show the user the current bids; only the highest bid but without repeating the same user. SELECT CusID, Max(Amount) FROM Bid WHERE SellID = 10 GROUP BY CusID ORDER BY Max(Amount) DESC This is the best I have achieved so far. This gives the CusID of each user with the maximum bid and it is ordered ascending. But I need to get the BidTime for each result as well. When I try to put the BidTime in to the query: SELECT CusID, Max(Amount), BidTime FROM Bid WHERE SellID = 10 GROUP BY CusID ORDER BY Max(Amount) DESC I am told that "Column 'Bid.BidTime' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause." Thus I tried: SELECT CusID, Max(Amount), BidTime FROM Bid WHERE SellID = 10 GROUP BY CusID, BidTime ORDER BY Max(Amount) DESC But this returns all the rows. No distinction. Any suggestions on solving this issue?

• Is it practical to program with your feet?

  - by bmm

  Has anyone tried using foot pedals in addition to the traditional keyboard and mouse combo to improve your effectiveness in the editor? Any actual experiences out there? Does it work, or is it just for carpal tunnel relief? I found one blog entry from a programmer who actually tried it: So now I can type using my feet for most of the modifier keys. I am using the pedals as I type this. I am still getting used to them, but the burning in my left wrist has definitely reduced. I think I can also type a little faster, but I am too lazy to do the speed tests with and without the pedals to verify this. On the negative side: Working out where to put your feet when you aren’t typing can be a little awkward. The pedals tend to move around the carpet, despite being metal and quite heavy. Some small spikes might have helped. Although the travel on the pedals is small, they are surprisingly stiff. Another programmer's experience: Anybody with hand pain must get foot pedals, since they can remove a tremendous load from your hands. I have two foot pedals, and use one for the SHIFT key, and the other for the CONTROL key. (I still type META by hand.) I have found that in the process of using the Emacs text editor to compose computer programs, I tend to use the SHIFT, CONTROL and META keys constantly, and it is easy to remove most of this load from one's hands.

• C# .NET: Descending comparison of a SortedDictionary?

  - by Rosarch

  I'm want a IDictionary<float, foo> that returns the larges values of the key first. private IDictionary<float, foo> layers = new SortedDictionary<float, foo>(new DescendingComparer<float>()); class DescendingComparer<T> : IComparer<T> where T : IComparable<T> { public int Compare(T x, T y) { return -y.CompareTo(x); } } However, this returns values in order of the smallest first. I feel like I'm making a stupid mistake here. Just to see what would happen, I removed the - sign from the comparator: public int Compare(T x, T y) { return y.CompareTo(x); } But I got the same result. This reinforces my intuition that I'm making a stupid error. This is the code that accesses the dictionary: foreach (KeyValuePair<float, foo> kv in sortedLayers) { // ... } UPDATE: This works, but is too slow to call as frequently as I need to call this method: IOrderedEnumerable<KeyValuePair<float, foo>> sortedLayers = layers.OrderByDescending(kv => kv.Key); foreach (KeyValuePair<float, ICollection<IGameObjectController>> kv in sortedLayers) { // ... } UPDATE: I put a break point in the comparator that never gets hit as I add and remove kv pairs from the dictionary. What could this mean?

• Alternative Python standard library reference

  - by Ender

  I love Python; I absolutely despise its official documentation. Tutorials do not count as library references, but that appears to be what they're attempting. What I really want is the ability to find a class in the standard library and view documentation for all of its properties and methods. Actionscript, MSDN, and Java all do this just fine (although each with their odd quirks). Where is this for python? For example, I wanted to sort a list. mylist.sort(). Awesome. But what if I wanted it sorted in descending order? Official documentation is not - much - help. Or what if I wanted to specify a key function? That's also supported: mylist.sort(key=lamba item: item.customVar)- but documented...where? I understand that Python's approach to OOP may not be equivalent to Java et. al. Maybe list isn't actually a class - maybe it's just a function that returns an iterable when the tachyon beams are set to glorious and the unboxed hyper enumeration is quantized, but...I don't care. I just want to know how to sort lists. (Apologies for the angst - too much caffeine today)

• Secure Webservice (WCF) without storing credentials on consumer application

  - by Pai Gaudêncio

  Howdy folks, I have a customer that sells a lottery analysis application. In this application, he consumes a webservice (my service, I mean, belongs to the company I work for now) to get statistical data about lottery results, bets made, amounts, etc., from all across the globe. The access to this webservice is paid, and each consult costs X credits. Some people have disassembled this lottery application and found the api key/auth key used to access the paid webservice, and started to use it. I would like to prevent this from happening again, but I can't find a way to authenticate on the webservice without storing the auth. keys on the application. Does anyone have any ideas on how to accomplish such task? ps1.Can't ask for the users to input any kind of credentials. Has to be transparent for them (they shouldn't know what is happening). ps2. Can't use digital certificates for the same reason above, not to mention it's easy to retrieve them and we would fall into the original problem. Thanks in advance.

• Force Oracle error on fetch

  - by Dan

  I am trying to debug a strange behavior in my application. In order to do so, I need to reproduce a scenario where an SQL SELECT query will throw an error, but only while actually fetching from the cursor, not while executing the query itself. Can this be done? Any error will do, but ORA-01722: invalid number seems like the obvious one to try. I created a table with the follwing: KEYCOL INTEGER PRIMARY KEY OTHERCOL VARCHAR2(100) I then created a few hundred rows with unique values for the primary key and the value l for the othercol. I then ran a SELECT * query, picked a row somewhere in the middle, and updated it to the string abcd. I ran the query SELECT KEYCOL, TO_NUMBER(OTHERCOL) FROM SOMETABLE hoping to get some rows of good data an then an error later. But I keep getting ORA-01722: invalid number on the execute step itself. I have gotten this behavior programmatically using ADO (with server-side cursor) and JDBC, as well as from PL/SQL Developer. How can I get the result I'm looking for? thanks Edit - meant to add, when using ADO, I am only calling Command.Execute. I am not creating or opening a Recordset.

• How to use SQLAlchemy to dump an SQL file from query expressions to bulk-insert into a DBMS?

  - by Mahmoud Abdelkader

  Please bear with me as I explain the problem, how I tried to solve it, and my question on how to improve it is at the end. I have a 100,000 line csv file from an offline batch job and I needed to insert it into the database as its proper models. Ordinarily, if this is a fairly straight-forward load, this can be trivially loaded by just munging the CSV file to fit a schema, but I had to do some external processing that requires querying and it's just much more convenient to use SQLAlchemy to generate the data I want. The data I want here is 3 models that represent 3 pre-exiting tables in the database and each subsequent model depends on the previous model. For example: Model C --> Foreign Key --> Model B --> Foreign Key --> Model A So, the models must be inserted in the order A, B, and C. I came up with a producer/consumer approach: - instantiate a multiprocessing.Process which contains a threadpool of 50 persister threads that have a threadlocal connection to a database - read a line from the file using the csv DictReader - enqueue the dictionary to the process, where each thread creates the appropriate models by querying the right values and each thread persists the models in the appropriate order This was faster than a non-threaded read/persist but it is way slower than bulk-loading a file into the database. The job finished persisting after about 45 minutes. For fun, I decided to write it in SQL statements, it took 5 minutes. Writing the SQL statements took me a couple of hours, though. So my question is, could I have used a faster method to insert rows using SQLAlchemy? As I understand it, SQLAlchemy is not designed for bulk insert operations, so this is less than ideal. This follows to my question, is there a way to generate the SQL statements using SQLAlchemy, throw them in a file, and then just use a bulk-load into the database? I know about str(model_object) but it does not show the interpolated values. I would appreciate any guidance for how to do this faster. Thanks!

• Create a HTML table from nested maps (and vectors)

  - by Kenny164

  I'm trying to create a table (a work schedule) I have coded previously using python, I think it would be a nice introduction to the Clojure language for me. I have very little experience in Clojure (or lisp in that matter) and I've done my rounds in google and a good bit of trial and error but can't seem to get my head around this style of coding. Here is my sample data (will be coming from an sqlite database in the future): (def smpl2 (ref {"Salaried" [{"John Doe" ["12:00-20:00" nil nil nil "11:00-19:00"]} {"Mary Jane" [nil "12:00-20:00" nil nil nil "11:00-19:00"]}] "Shift Manager" [{"Peter Simpson" ["12:00-20:00" nil nil nil "11:00-19:00"]} {"Joe Jones" [nil "12:00-20:00" nil nil nil "11:00-19:00"]}] "Other" [{"Super Man" ["07:00-16:00" "07:00-16:00" "07:00-16:00" "07:00-16:00" "07:00-16:00"]}]})) I was trying to step through this originally using for then moving onto doseq and finally domap (which seems more successful) and dumping the contents into a html table (my original python program outputed this from a sqlite database into an excel spreadsheet using COM). Here is my attempt (the create-table fn): (defn html-doc [title & body] (html (doctype "xhtml/transitional") [:html [:head [:title title]] [:body body]])) (defn create-table [] [:h1 "Schedule"] [:hr] [:table (:style "border: 0; width: 90%") [:th "Name"][:th "Mon"][:th "Tue"][:th "Wed"] [:th "Thur"][:th "Fri"][:th "Sat"][:th "Sun"] [:tr (domap [ct @smpl2] [:tr [:td (key ct)] (domap [cl (val ct)] (domap [c cl] [:tr [:td (key c)]]))]) ]]) (defroutes tstr (GET "/" ((html-doc "Sample" create-table))) (ANY "*" 404)) That outputs the table with the sections (salaried, manager, etc) and the names in the sections, I just feel like I'm abusing the domap by nesting it too many times as I'll probably need to add more domaps just to get the shift times in their proper columns and the code is getting a 'dirty' feel to it. I apologize in advance if I'm not including enough information, I don't normally ask for help on coding, also this is my 1st SO question :). If you know any better approaches to do this or even tips or tricks I should know as a newbie, they are definitely welcome. Thanks.

• How to cache L2E entity without attach/detach?

  - by Eran Betzalel

  The following code will select a key/value table in the DB and will save the result to the cache: using (var db = new TestEntities()) { if(Cache["locName_" + inventoryLocationName] != null) return Cache["locName_" + inventoryLocationName]; var location = db.InventoryLocationsSet.FirstOrDefault( i => i.InventoryLocationName.Equals( inventoryLocationName, StringComparison.CurrentCultureIgnoreCase)); db.Detach(location); // ???? Cache["locName_" + inventoryLocationName] = location; return location; } But it doesn't work well when I'm trying to use the cached object. Of course, the problem is the different ObjectContext, so I use Attach/Detach and then the problem solves but with a codding horror price: db.Attach(locationFromCache); // ???? try { // Use location as foreign key db.SaveChanges(); } finally { db.Detach(locationFromCache); // ???? } So, how can I use cached objects without using attach/detach methods? What happens if more than one user will have to use this cached object? Should I put the whole thing in a CriticalSection?!

• NetBeans Tips and Tricks

  - by cdmckay

  I just saw an Eclipse tips & tricks post and was wondering if anyone had any tips & tricks for my IDE of choice: NetBeans. Here's a few I know and find to be useful: Removing a package: After you remove a package in NetBeans, it sticks around as a grayed-out package in your Project view. To get rid of that, switch to Files view and delete the directory. Alt-Insert (in Windows) opens up a Generate submenu at your cursor. A nice shortcut for quickly generating getters/setters (among other things). Selecting a chunk of code, right-clicking and then clicking "Refactor Introduce Method" will have NetBeans introduce a method, complete with arguments and return value. Of course you have to make sure the chunk of code only has one return value. Sometimes when you run a build and it crashes, the Java window sticks around at the bottom. I used to just click X until Windows let me End Task, but there's a nicer way to get rid of them. Click "Run Stop Build/Run" and NetBeans will close the window for you. It'll even let you close multiple applications at once. These may seem obvious to grizzled NetBeans developers, but I thought they might be useful for NetBeans newbs like me. Anyone else have any tips/tricks to share? Here are some from the comments: NetBeans allows for code templates. You can even add yours on the Code Templates tab under the Editor settings on the Options window. Some examples: Type sout and hit the tab key as a shorcut for System.out.println("") Type psvm and hit the tab key as a shorcut for public static void main(String args[]) {} Ctrl Shift C: Comments out the selected block of code. Alt Shift F: Formats the selected block of code. Ctrl E: Deletes current line. Ctrl Shift I: Fixes your imports, handy if you've just written a piece of code that needs a lot of packages imported.

• Registry access error when Migrating ASP.NET application to IIS7

  - by fande455

  I'm running windows 7 64-bit and iis7. I'm trying to setup a web application that was previously in iis6 on XP. It's giving me the error below. I've added the network service user to the Performance Monitor Users group to no avail. Access to the registry key 'Global' is denied. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.UnauthorizedAccessException: Access to the registry key 'Global' is denied. ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}\ASPNET on IIS 5 or Network Service on IIS 6) that is used if the application is not impersonating. If the application is impersonating via , the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user. To grant ASP.NET access to a file, right-click the file in Explorer, choose "Properties" and select the Security tab. Click "Add" to add the appropriate user or group. Highlight the ASP.NET account, and check the boxes for the desired access.
